1. What is the frequency?
2. Explain what is meant by modulation and modulation purposes mentioned (min. 3)!
3. What is an Access Point?
4. Explain the meaning of WPAN and WLAN!
5. List the advantages of using a wireless network (wireless network)!
Answer Essay:
1. Frequency is a concept discussed in periodic movements of objects.
2. Modulation is the process of mixing the two signals into one signal. Usually the mixed signal is a signal of high frequency and low frequency signals.
Purpose Modulation:
Ø Transmission become efficient or facilitate broadcasting.
Ø A hardware problem becomes easier.
Ø For multiplexing, the process of merging some of the information signal to be routed together through a single transmission channel.
3. Access Point is a node that has been configured specifically to a WLAN (Wireless Local Area Network)
4. WPAN is a wireless communication network of the other devices with other devices in very close quarters, centered near interconecting device, just a few meters away. While WLAN is a computer network that uses radio waves as a medium for data transmission.
5. Advantages of a wireless network (LAN):
Ø Mobility
Ø installation speed
Ø Flexibility place
Ø The cost of maintenance and removal cheaper
Ø The ability to reach
